Texas Instruments  TLV320AIC34EVM-K

The TLV320AIC34EVM is in Texas Instruments‘ modular EVM form factor, which allows direct evaluation of the device performance and operating characteristics, and eases software development and system prototyping. This EVM is compatible with the 5 6K Interface Evaluation Module (SLAU104) and the HPA-MCUINTERFACE (SLAU106) from Texas Instruments and additional third-party boards whichsupports the TI Modular EVM format.

The TLV320AIC34EVM-K is a complete evaluation/demonstration kit, which includes a USB-based motherboard called the USB-MODEVM Interface board and evaluation software for use with a personalcomputer running the Microsoft Windows operating systems.

The USB connection from the PC provides power, control, and streaming audio data to the EVM for reduced setup and configuration. The EVM also allows external control signals, audio data, and power foradvanced operation, which allows prototyping and connection to the rest of the evaluation/development system.
